[jira] [Commented] (DRILL-623) Unable to run query containing
quoted schema name
[ https://issues.apache.org/jira/browse/DRILL-623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13988517#comment-13988517 ]
Venki Korukanti commented on DRILL-623:
---------------------------------------
"hive.default" is considered as one schema when quoted with backticks, but it is a two level schema "hivestg" and "default". Try the following query:
{code}
SELECT * FROM hivestg.`default`.integer_table;
{code}

> Issue Type: Bug

> This is particularly for the Hive storage-engine where the schema name is composed of a root followed by the storage-engine's own schema name. E.g., configuring Hive leads to a schema name "hivestg.default":
> 0: jdbc:drill:schema=hivestg> select * from INFORMATION_SCHEMA.SCHEMATA;
> +--------------+-------------+--------------+
> | CATALOG_NAME | SCHEMA_NAME | SCHEMA_OWNER |
> +--------------+-------------+--------------+
> | DRILL | hivestg.default | <owner> |
> | DRILL | hivestg | <owner> |
> | DRILL | dfs.default | <owner> |
> | DRILL | dfs | <owner> |
> | DRILL | cp.default | <owner> |
> | DRILL | cp | <owner> |
> | DRILL | INFORMATION_SCHEMA | <owner> |
> +--------------+-------------+--------------+
> 7 rows selected (0.131 seconds)
> Given tables inside hivestg.default as follows:
> 0: jdbc:drill:schema=hivestg> select * from INFORMATION_SCHEMA.`TABLES`;
> +---------------+--------------+------------+------------+
> | TABLE_CATALOG | TABLE_SCHEMA | TABLE_NAME | TABLE_TYPE |
> +---------------+--------------+------------+------------+
> | DRILL | hivestg.default | sneaky | TABLE |
> | DRILL | hivestg.default | bit_table | TABLE |
> | DRILL | hivestg.default | stinyint_table | TABLE |
> | DRILL | hivestg.default | no_null_integer_table | TABLE |
> | DRILL | hivestg.default | real_table | TABLE |
> | DRILL | hivestg.default | integer_table | TABLE |
> A generated query would look as follows:
> SELECT * FROM `hivestg.default`.`integer_table`
> This fails to execute with the following error:
> 0: jdbc:drill:schema=hivestg> SELECT * FROM `hivestg.default`.`integer_table`;
